TERMINAL CONNECTEB.

Application am April as, 1924. Serial in. 709,589.

My invention relates to terminal connecters and provides improved meanswhereby wire conductors may be brought into firm mechanical andelectrical union with terminal contacts without the aid of solder andscrews.

In carryin out my invention the terminal contact mem er is formed with apassage therethrough having angularly related ors which receive aconductin wire ent ccnt'orm to the passage and held in one branch of thepassage by a surrounding element of the container, this surroundingelement being preferably in the nature of a 7.55 metallic sleeve heldwithin a carrier of in- :-;uiating material. P

The invention will be more fully explained connection with theaccompanying drawin which Fig.1 is a longitudinal sec- Ill w tional viewof an electric coupling whose contacts are assembled with conductingwires in accordance with the referred embodiment of the invention; Fig.2 is a ion gitudinal view, partially in section of one of the couplingmembers shown in Fig. 1; Fig.

3 is a sectional view on line 3-3 of Fig. 1; Fig. i is a longitudinalsectional view of another form of connector; and Fig. 5 is a perspectiveview of one of the cylindrical metallic contact members.

Like parts are indicated by similar characters of reference throughoutthe didercnt figures.

Each coupling member shown in Figs. l. to t inclusive includes aninsulating contact carrier l-having, in Fig- 4:, one bore 2 and, inFigs. 1, 2 and 3, two such bores. Each bore contains a cylindricalmetallic sleeve or I tubular element 3 having rims 3 engaging shoulders2 each having a cylindrical bore, held tightly within the bore of thecorre sponding contact carrier. A cylindrical rne=- tallic contactmember i is snugly received in the bore of each sleeve and has a sinuouspassage formed with an intermediate portion 5 extending transverselytherethrough and narrower longitudinal end portions 6 and 7 at theoutside of and extending respectively toward the ends of this contactmember. A wire 8 passes through said sinuous passage and is tightlyengaged between themetallic sleeve and the nvlindrical (2011- tricalunion of the wire with the contact member 4; to which it extends.

In the structure shown in Figs. 1 and 2, each of the contactmembers 4 ofthe left hand coupling member has a split and hollow plug continuation'9 and the members uponthe other can ling member have socketcontinuations 10 w ich receive the plugs 9.

In the structure of Fig. 4 the contact member f the left-hand couplingmember receives an inwardlyspring pressed contact 11 engaging the buttend 12 of the complemental contact. The carrier llfor this lattercontact is. provided with two bayonet pins 13 receivable in bayonetslots 14L formed in the shell 15 which permanently holds the left handcarrier. J

In assembling the contact carriers with the contacts of my invention thewires are looped into the contacts before the contacts are assembiedwith the carriers whereafter the contacts are drawn mto the boresof thef carriers.

It will be observed that the cylindrical contour at each cylindricalcontact member is intact except at the end portions of the passage toenable engagement'of the contact members with the enclosingsleeves inthe zones of the ends 01": the passage.

is ebvieus that changes may be made without departing from the spirit ofmy inventicn.

Having thus described my invention I claim as new and desire to secureby Letters Patent the following 2- in a terminal connecter, acarrienmember formed transversely provide in conjunction With saidtransverse o ening a Wire receiving passage of sinuous s ape, thematerial of said Wire receivin A the recess ad acent thereto for contactwith memos the Well of the bore in said carrier member to preventtilting movement of the contact member Within said bore. m In Witnesswhereof, I hereunto subscribe my name.
